Instructions for AZ1117CH-3.3TRG1

1. Installation:

   • Ensure the input voltage is within the specified range of 2.5V to 5.5V.
   • Place the regulator on a suitable heatsink if operating near maximum output current to prevent overheating.

2. Output Configuration:

   • The AZ1117CH-3.3TRG1 provides a fixed output voltage of 3.3V. No external resistors are required for voltage setting.

3. Capacitor Requirements:

   • Use a minimum of 1μF ceramic capacitor on both input and output for stability.
   • For better transient response and noise filtering, larger capacitors (e.g., 10μF) can be used.

4. Thermal Considerations:

   • Monitor the junction temperature not to exceed 125°C.
   • If the power dissipation exceeds 1.6W, consider additional cooling methods or reducing the load.

5. Operation:

   • The device has a low quiescent current of 0.4mA, making it suitable for battery-operated devices.
   • Ensure the dropout voltage is considered in your design, especially at higher output currents.

6. Handling:

   • Follow proper anti-static precautions during handling to avoid damaging the component.
